To calculate molarity, the volume should be expressed in which unit?
Answer and explanation
Correct answer: Litre
Molarity is defined as the number of moles of solute divided by the volume of the final solution measured in litres. Its unit is mol L⁻¹, commonly written as M. Therefore the volume must be converted to litres before calculation. Milligram and kilogram measure mass, while mole measures amount of substance, so option A is the only suitable volume unit.
